在有源网络综合电路中,负阻抗变换器几乎是不可缺少的一种有源四端网络,这种负阻抗变换器常与无源四端网络链接在一起,或者链接后再与其它无源四端网络联接来实现某种网络函数,因而负阻抗变换器与无源网络链接的等效参数是有源网络综合电路运算的基本组成部分。现在应用负阻抗变换器的各种有源网络综合方法中,例如Linvill[1][2],Kinariwala[3],Yanagisawa[4],sandberg[5]及Sipress[6]等倡议的方法,应用负阻抗变换器有的是反压式的,有的是反流式的,有的用[a]参数表示,有的用[h]或[g]参数表示。负阻抗交换器与无源网络的联接型式也是多种多样的。要求实现的函数也不同,有的是转移函数,有的是策动点阻抗或导纳。这些含有负阻抗变换器的网络分析,虽然可以根据具体电路直接 In the active network synthesis circuit, the negative impedance converter is almost indispensable active four-terminal network, this negative impedance converter often with four-terminal passive network link together, or after the link with other passive Four-terminal network connection to achieve some kind of network function, so the negative impedance converter and passive network link equivalent parameters is the basic components of the active network integrated circuit operation. Nowadays, a variety of active network synthesis methods such as Linvill [1] [2], Kinariwala [3], Yanagisawa [4], Sandberg [5] and Sipress [6] Some of the negative impedance transformers are of the anti-voltage type, some of them are of the reverse type, some of which are represented by [a] parameters and others by [h] or [g] parameters. Negative impedance switch and passive network connection type is also varied. Required to achieve the function is different, some transfer function, and some are driven point impedance or admittance. These contain a negative impedance transformer network analysis, although it can be straightforward depending on the specific circuit
